Inspire announced the publication of its feasibility study results
in the May 2012 edition of the Laryngoscope journal.

Inspire conducted commercial implants in Germany, Italy and The
Netherlands.

Inspire has completed a Series C financing round of $14.5 million. The
funds will be used to support clinical trial patient follow-up, U.S.
regulatory submissions, and expansion of commercial activities in
Europe. Participating in this round of financing are new investors,
Medtronic and TGap Ventures, and existing investors, including Kleiner
Perkins Caufield & Byers, US Venture Partners, Synergy (News - Alert) Life Science
Partners and GDN Holdings.

Additionally, Laryngoscope, the journal of the American Laryngological,
Rhinological and Otological Society published in its May issue the
results of two earlier clinical trials conducted by Inspire
investigators. The publication reported that Inspire® Upper Airway
Stimulation (UAS) therapy is safe and efficacious in a select group of
patients with moderate to severe OSA who cannot or will not use CPAP as
primary treatment. The abstract of the study titled, Implanted upper
airway stimulation device for obstructive sleep apnea, is available here.

"Inspire has broadened its investor base, finished enrollment in its
STAR pivotal trial, and completed commercial implants in three European
countries," said Dr. Glen Nelson, Chairman of the Board of Inspire
Medical Systems. "Achievement of these critical milestones is a
testament to the experience and ability of Inspire's leadership team."

Inspire previously announced receipt of its CE Mark in 2010, and to date
has completed commercial implants in Germany, Italy and The Netherlands.
Inspire has a strong European team focused on the broader adoption of
Inspire therapy in Europe.

"Obstructive Sleep Apnea is a prevalent disorder affecting over 15
million people in The United States alone. A substantial number of these
patients are unable to achieve consistent benefit from conservative
therapies. The swift enrollment of our STAR pivotal trial demonstrates
the significant interest that patients have in Inspire therapy. It also
reflects the strong commitment our physician investigator group has made
to develop this promising therapy," said Tim Herbert, President and CEO
of Inspire Medical Systems. "Our focus now is to gain regulatory
approvals and to secure reimbursement mechanisms so that this patient
group will have access to our breakthrough technology."

About Obstructive Sleep Apnea (OSA)

OSA is characterized by repeated episodes of upper airway collapse
during sleep. Patients with OSA stop breathing frequently during their
sleep (apnea), often for a minute or longer. Fragmented sleep with
recurrent awakening, called arousals, leads to daytime sleepiness and
fatigue. Depending on the degree of severity, OSA can be a potentially
life-threatening condition. Recent research suggests that a person with
undiagnosed sleep apnea or a person that is noncompliant to treatment of
their sleep apnea is at increased risk for: heart attack, stroke, weight
gain, high blood pressure and heart failure.

About Inspire®Upper Airway Stimulation (UAS)
Therapy

InspireUpper Airway Stimulation (UAS) therapy is a dynamic,
implantable therapy that works with the body's natural physiology to
prevent airway obstruction during sleep. While the patient sleeps,
Inspire therapy is designed to deliver mild stimulation to the
hypoglossal nerve synchronous with each breathing cycle. The stimulation
is delivered to the muscles that control the base of tongue, preventing
the tongue from collapsing and obstructing the airway. Patients are able
to activate the Inspire therapy using a handheld programmer. In contrast
to other surgical procedures to treat sleep apnea, Inspire therapy does
not require removing or permanently altering an OSA patient's facial or
airway anatomy.

About Inspire Medical Systems

Inspire Medical Systems, based in Minneapolis, Minnesota, is the world's
leading developer of innovative, implantable neurostimulation
technologies to treat Obstructive Sleep Apnea (OSA). Utilizing
